Elderly man hobbled by passing train

An 84-year-old man lost some of his toes when he wandered onto the subway tracks Sunday and was hit by an oncoming 4 train. Anatoliy Zilberman, who lives in an assisted living facility and uses a walker, was on the tracks north of Union Square when an express track zoomed into the station. Zilberman has Alzheimer's disease, said police, and it was unclear how he made it onto the tracks.
